The levels of sum-DDT, PCBs, and HCB in fish liver and crab hepatopancreas from the Kristiansand fjord area in Norway have been determined (fig. 1). The respective mean levels (fat weight basis) in stationary fish species and crabs are given in table I. The levels of PCBs and sum-DDT were about the same, and the HCB level two to one hundred times higher than corresponding levels reported for codfish (liver) from several harbours along the Norwegian coasts (Brevik et al. in press). The levels calculated on a wet weight basis, found is stationary fish from the harbour of Kristiansand and Topdals-fjord were two to three times higher than those in crabs. Calculated on a fat weight basis, however, the levels in stationary fish and crabs were much more similar (table II). The harbour area was more contaminated with PCBs and HCB than the other sites examined. It seems impossible, however, on the basis of present data to further pinpoint sources of the relatively high degree of HCB contamination in the Kristiansand fjord area.
已测定挪威克里斯蒂安桑峡湾地区鱼类肝脏和蟹类肝胰腺中总滴滴涕、多氯联苯和六氯苯的含量（图1）。表I给出了定居鱼类和蟹类中各自的平均含量（以脂肪重量计）。多氯联苯和总滴滴涕的含量大致相同，六氯苯的含量比挪威沿海几个港口鳕鱼（肝脏）报告的相应含量高2至100倍（Brevik等人，即将发表）。以湿重计算，在克里斯蒂安桑港和托普达尔峡湾的定居鱼类中发现的含量比蟹类中的高2至3倍。然而，以脂肪重量计算，定居鱼类和蟹类中的含量更为相似（表II）。港口区域的多氯联苯和六氯苯污染比其他检测地点更严重。然而，根据目前的数据，似乎不可能进一步确定克里斯蒂安桑峡湾地区六氯苯污染程度相对较高的来源。
